title: Sinoatrial node electrical activity recording through intracavitary leads.
abstract: Electrical activity of the sinoatrial node was recorded on bipolar intracavitary leads at superior vena caval-right atrial junction in ten patients. These recordings may be important for practical purposes, but they still have many limitations concerning the amount of the atrial potentials which can be recorded together with sinoatrial potential.
